To all (whom it may concern.

Beit known that I, EDWARD A. Soggy, a citizen of the United States, residing at Bed-ford, in the county of Lawrence and State of Indiana, have invented new and useful Improvements in Stone-Channeling Machines, of which the following is a specification.

'iihis invention relates to stone channeling machines. The object isto .provaide a more rigid frame construction capable of better withstanding the severe stresses and shocks to which suchmachines are subjected when in use. The clamps which. carry the drills, slide up and down on the chairboards'or slides, and when the drills strike the stone they are working on, the sudden stoppage of the clamps carrying the drills reduces such severe shocks, that unless it 1e'chair boards or slides are of exceptionally rigid, strong construction and bracing, looseness soon develops in the slides, thereby .renderingthe .inachine less eilicient inuse.

To produce a construction of the desired permanent rigidity, two slide .members comprising a pair extend parallel tromthe bottom to the top, on each side of the machine. The members of each pair of slides are rigidly connected together at their .end .portions, and at a plurality of places inter mediate their ends. Each ,pair is .alsoconnected to the other pair by tie .rods and specially designed braces.

Other objects and advantages will appear from the specification taken in connection with the accompanying drawing in which Fig. '1 is a perspective view of the channeling machine.

Fig. 2 is a fragmental perspective view from a different angle, of the lower portion Of a pair of slides and adjacent parts, with lever removed.

Fig. 3 is a sectional elevation on line 3 3 of Fig. 1 showing the upper portion of a pair of slides together with the cross braces.

4 is a sectional plan on line 44 of Fig. 1, showing the manner in which brace 26 is spaced back to provide clearance for clamp 27.

The same numerals refer to similar parts in the different views.

Connected to each side of the bed frame 1 is a pair of slides or chair boards 2, 3, extending parallel vertically upwards. At its lower end, slide 2 is connected by bolts 4,

5, 7, .8, and brace6 tothe horn bracket .9. Horn .braclrett) issecuredto the frame 1 .by bolts '10, .11. Slide 3 is secured to frame- 1 by bolts 12, 13. Slides 2, andfi, about half way up are connected by bolts 14, 15, preferably to an integral bracket or brace 16 which latter is suitably connected to frame 1 as shown. Still ffurther upward, slides f2 and 3 areconnected by bolts 17, 18,119, 21}, preferably to an intermediatecross brace "21. At the upper ends, slides 2 and3 are connected by bolts '22, 23, 24, 25 preferablyto a top cross brace 26.

Brackets 16 and braces 21 and 26 where they span the space between a pair of slides are suitably spaced back to provide clearance for clamp 27 which moves on ,theslide and carries the upper ends of the drills in a manner well known in the art. Braces 21 have preferably integral extensions 28 providing upper and lower flanges 29, 30, forming flanged bracing channels or seats for the struts or braces31,whichare secured thereto by bolts '32. Braces 26 have integral eXtensions 33, proi riding upper and lower flanges 34, 35 torming'flanged bracing channels or seats for the struts or braces'36 which are secured thereto bolts 37. Tie rods 3f8extend across from the top of each pair of slides to the brackets 16 as shown. The oppositeouter sides of extensionsx28 are preferably closer together than the opposite outer sides of extensions ,to provide clear-- ance paststruts [31 for tie rods 38. Angle braces connect'braces with frame 1 of machine. Mounted ,on each 'brace is a bracket 40 carrying sheave '41, over which passes a chain 42 connected at one end with clamp 27 and at the other end with windlass 43 secured on bracket 16 by bolts 44. This chain 42 is for raising clamp 27 when desired.

On "the drawing, the machine is shown without the drills, for the sake of clearness. When the machine is to be operated, the clamps 27 are hoisted up beyond the ends of slides 2 and 3 and lowered onto the ground. Drills are then slid through slots in clamps 27 which are similar to slots 47 in clamps 46, and fastened by wedges driven in holes similar to holes 48 in clamps 46. The clamps 27 with drills attached, are then hoisted up over the ends of slides 2 and 3, and lowered till the drills project down through slots 47 in clamps 46 the desired distance. lVedges are then driven in holes 48 in clamps 46 to secure the drills firmly to clamps 46. The

chains 42 are then detached from clamps :27,-

and the machine is ready to be operated. hen the drills are in position as described, they appear similar to the manner shown in Patent 105,391, except that they are fastened by wedges. But this wedge fastening is old and well known in the art. As the drills rigidly connect clamps 27 and 46, the drills and clamps are reciprccated up and down by the lever do which engages clamp 46, and is oscillated up and down by mechanism well known in the art.

I claim:

1. A stone channeling machine comprising, a bed frame, a pair of spaced slides connected at each side of the bed frame and extending upwardly therefrom, the adjacent portions of the outer faces of the slides of each pair being substantially in a plane extending longitudinally of the machine, a cross brace connecting together the slides of each pair, both cross braces being at substantially the same height, and strut bracing means comprising two spaced members extending side by side in a direction transversely of the machine and connected to the two cross braces.

2. The machine set forth in claim 1 in which the connection between each cross brace and strut member comprises a portion of one .eated between opposite seats on the ether.

3. A stone channeling machine comprising, a bed frame, a pair of spaced slides con nected at each side of the bed frame and ex tending upwardly therefrom, the adjacent portions of the outer faces of the slides of each pair; being substantially in a plane extending longitudinally of the machine, a cross brace connecting together the slides of each pair, and strut bracing means ex tending transversely of the machine and connected to the two cross braces, the connection between each cross brace and strut bracing means comprising a'portion of one seated between opposite seats on the other.

4. A stone channeling machine comprising, a bed frame, a pair of spaced slides connected at each side of the bed frame and extending upwardly therefrom, the adjacent portions of the outer faces of the slides of each pair being substantially in a plane extending longitudinally of the machine, a cross brace connecting together the slides of each pair in the region of the upper ends of the slideswith the intermediate portion of each cross brace spaced back from the inner faces of the slides to which it is connected whereby drill clamps havingopposite grooves adapted to engage adjacent portions of the slides may be slid on or off over the upper ends of the slides without changing the position of the cross brace, and strut bracing means extending transversely of the machine and connecting the two cross braces together.

5. The machine set forth in claim 4: with a sheave bracket mounted intermediate the slides oneach cross brace.

6. A stone channeling machine comprising, a bed frame, a pair of spaced slides connectedat each side of the bed frame and extending upwardly therefrom, the adjacent portions of the outer faces of the slides of each pair beingsubstantially in a plane extending longitudinally of the machine, a top cross brace connecting together the slides of each pair in the region of the upper ends of the slides, an intermediate cross brace connecting together the slides of each pair in a region substantially below the top cross braces, top strut bracing means extending transversely of the machine and connected to the two top cross braces, intermediate strut bracing means extending transversely of the machine and connected to the two intermediate cross braces, and a bracket connecting together the slides of each pair, the

brackets being below the intermediate cross braces.
